Tonight my server updated with the latest gnome-shell:amd64 3.36.4-lubuntu~20.04.2 update and since applying this update the server has repeatedly gone into a hard drive stasis every 20 minutes (approx). The drives only come alive again by me pressing the server's power button momentarily and after another 20 minutes it does the same thing again. My server is headless and until tonight has never suffered this issue.
Is there a config setting that has been changed by this update and if so which one and how do I resolve it please?
